Expose list of workers and their states via API

[peteyb]

I would like a method to expose the current state of workers so that I can perform a livenessProbe health check in Kubernetes.

For context, we run django-q via python manage.py qcluster within docker containers hosted in GCP via Kubernetes Engine. We have a redis backend which has 1 master and 2 slaves.

In the scenario where the master node fails one of the slaves is automatically promoted to be the new master. When this happens the django-q workers stop processing any new requests and appear to be hung on the old tasks.

If we perform the broker.ping() it comes back True as the redis slave still connects.

We need a way to determine the state of the workers in this scenario so that we can restart the container to get things working again.
